Interfacial negative magnetization in Ni encapsulated layer-tunable nested MoS₂ nanostructure with robust memory applications.

ABSTRACT: Combining interfacial interactions and layer-number tunability, the evolution of magnetism in low-dimensional diamagnetic systems like MoS₂ is indeed an interesting area of research. To explore this, Ni nanophases with an average size of 12 nm were encapsulated in MoS₂ and the magnetization dynamics were studied over the temperature range of 2-300 K. Surprisingly, the newly formed hybrid nanostructure was found to have a negative magnetization state with giant exchange bias that showed a reversible temperature-induced increase in both spin magnetic moment and coercivity. Density functional theory calculations proved an interfacial charge transfer interaction with a spin-polarized density of states. The magnetization state, along with giant exchange correlation among t
